Desmos Art: A Definitive Guide to Computational Sketching (How to Recreate Our Redditlady and Redditdog Using an Online Graphing Calculator)
If you’re of the type who enjoys playing around with graphing calculator, then you might be interested in the so-called Desmos Art. These are basically pictures and animations created in Desmos primarily through the clever use of equations and inequalities — among other features such as tables, animating sliders and regression models. Indeed, if you go to this official staff pick page, you should see that a whole bunch of creative artworks were already being created — anything from cartoon characters, landscape to logos and portraits.
But here’s a problem: when you reach a Desmos artwork page, you get to see the end-result with all the equations and inequalities, without necessarily having any clue about how the sketching process comes about from the beginning to the end. Why does this weird-looking equation pop out from nowhere? How did the author know that $3.982$ is the leading coefficient to use? And how did those numbers get so precise up to four decimals digits?
To remedy this situation, we came up with a laborious and interesting solution: we decided to go out there and create a new Desmos sketch from scratch, and work backward to comment a bit on the steps, procedures and reasoning involved in the sketching process — as we go through the different stages and portions of the drawing.
And with that, let’s proceed straight into our Desmos Art guide in Computational Sketching, which — as you might have guessed — is going to be both fun and informative — even if you have no intention whatsoever of using any graphing calculator in the near future. 🙂 More
